1322 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
1323
1324 Usage: $0 [OPTION]... [VAR=VALUE]...
1325
1326 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1327 VAR=VALUE. See below for descriptions of some of the useful variables.
1328
1329 Defaults for the options are specified in brackets.
1330
1331 Configuration:
1332 -h, --help display this help and exit
1333 --help=short display options specific to this package
1334 --help=recursive display the short help of all the included packages
1335 -V, --version display version information and exit
1336 -q, --quiet, --silent do not print \`checking ...' messages
1337 --cache-file=FILE cache test results in FILE [disabled]
1338 -C, --config-cache alias for \`--cache-file=config.cache'
1339 -n, --no-create do not create output files
1340 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1341
1342 Installation directories:
1343 --prefix=PREFIX install architecture-independent files in PREFIX
1344 [$ac_default_prefix]
1345 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1346 [PREFIX]
1347
1348 By default, \`make install' will install all the files in
1349 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1350 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1351 for instance \`--prefix=\$HOME'.
1352
1353 For better control, use the options below.
1354
1355 Fine tuning of the installation directories:
1356 --bindir=DIR user executables [EPREFIX/bin]
1357 --sbindir=DIR system admin executables [EPREFIX/sbin]
1358 --libexecdir=DIR program executables [EPREFIX/libexec]

1444
1445 Some influential environment variables:
1446 CC C compiler command
1447 CFLAGS C compiler flags
1448 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1449 nonstandard directory <lib dir>
1450 LIBS libraries to pass to the linker, e.g. -l<library>
1451 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1452 you have headers in a nonstandard directory <include dir>
1453 CPP C preprocessor
1454 CXX C++ compiler command
1455 CXXFLAGS C++ compiler flags
1456
1457 Use these variables to override the choices made by `configure' or to help
1458 it to find libraries and programs with nonstandard names/locations.
